Why is this an issue?
There is no need to multiply the output of Random's nextDouble method to get a random integer. Use the
nextInt method instead.
This rule raises an issue when the return value of any of Random's methods that return a floating point value is converted to an
integer.
Noncompliant code example
Random r = new Random();
int rand = (int)r.nextDouble() * 50; // Noncompliant way to get a pseudo-random value between 0 and 50
int rand2 = (int)r.nextFloat(); // Noncompliant; will always be 0;
Compliant solution
Random r = new Random();
int rand = r.nextInt(50); // returns pseudo-random value between 0 and 50
